Ghost Work

The hidden human labor that powers 'automated' AI and web services, named in the 2019 book by Mary L. Gray and Siddharth Suri.

concept May 28, 2020

The Scaling Hypothesis

The claim that broad capability emerges mainly from scaling up simple models with more compute and data.

concept May 11, 2021

Neuro-Symbolic AI

An approach that combines neural-network learning with symbolic reasoning to get the strengths of both.

concept May 23, 2023

Multi-Agent Debate

A method where several LLM copies propose and argue over answers across rounds, improving factuality and reasoning over a single pass.

concept November 4, 2023

Narrow AI vs General AI

The distinction between systems that excel at specific tasks and the long-sought goal of broad, flexible intelligence.

concept March 19, 2024

The AI reverse acqui-hire

A deal pattern where a big tech firm hires a startup's founders and licenses its technology, absorbing the team without a formal acquisition.

concept March 27, 2024

Agentic Workflows

Andrew Ng's framing of four design patterns - reflection, tool use, planning, and multi-agent collaboration - that make LLMs act like agents.

concept April 2, 2024

Many-Shot Jailbreaking

A jailbreak that defeats LLM safety training by stuffing the prompt with many fake examples of the model complying with harmful requests.

concept May 8, 2024

AI for science

A pattern in which learned models replace or accelerate physical simulation and brute-force search across biology, weather, materials and mathematics.

concept June 7, 2024

Mixture-of-Agents (MoA)

A layered method that stacks several LLMs so each refines the prior layer's outputs, beating GPT-4 Omni on AlpacaEval 2.0 with open models.

concept June 20, 2024

The AI bubble debate

The argument over whether AI investment has run far ahead of revenue and will deflate, or is a justified infrastructure buildout.

concept June 20, 2024

The AI ROI gap

The gap between massive AI investment and measurable returns - reflected in modest enterprise adoption and a revenue base far below infrastructure spend.

concept July 23, 2024

Foundation-model commoditization

The thesis that base AI models are becoming interchangeable commodities as open models catch up and per-token prices collapse.

concept September 19, 2024

Contextual Retrieval

Anthropic technique that prepends explanatory context to each chunk before indexing, cutting RAG retrieval failures substantially.

concept November 12, 2024

LLMflation

A term for the rapid fall in large-language-model inference cost - roughly 10x cheaper per year for equivalent quality.

concept January 3, 2025

The AI capex supercycle

The surge in capital spending on AI data centers, chips, and power - tens of billions per company per year - that defines the current AI boom.

concept January 21, 2025

Frontier lab economics

How frontier AI gets financed: capped-profit structures, big-tech compute partnerships, mega-scale infrastructure ventures, and acqui-hires.

concept February 2, 2025

Vibe Coding

Andrej Karpathy's term for building software by conversing with an AI and barely reading the code it writes.

concept September 22, 2025

Circular financing in AI

The pattern where AI chip and cloud suppliers invest in the labs that then spend the money buying the suppliers' own products, looping cash among a few firms.
